摘要 以3种典型土壤类型新积土、塿土、黄绵土为研究对象,分析了水田建设对不同类型土壤质地的影响。结果表明:改水田后,新积土与塿土各土层的颗粒组成改变,但土壤质地未发生变化;黄绵土各土层的土壤颗粒含量变化较大,表现为0~20 cm土层,粘、粉粒含量上升,砂粒含量下降,其余土层粘、粉粒含量下降,砂粒含量上升,变化过程波动较大,影响了黄绵土的土壤质地。 Based on three typical soil types,new soil,bauxite and loess soil,the effects of paddy field construction on different types of soil texture were analyzed.The results showed that after changing the paddy field,the particle composition of the new soil and bauxite soil layers changed.However,the soil texture did not change;the soil particle content of each layer of loess soil changed greatly,showing 0~20cm soil layer.the content of stickiness and powder increased;the content of sand decreased;the content of other soil layer decreased;the content of powder decreased and the content of sand ascended;the process of variation fluctuated greatly,affecting the soil texture of loess soil.
